UNITED STATES MORRIS H. DEVORE, OF ST. LOUIS, MISSOURI.

JOURNAL- BEARING.

SPEGIFIGATION forming part of Letters Patent No. 669,478, dated March 5, 1901.

Application filed July 16, 1900.

T aZZ whom/it may concern.-

Be it known that I, Monnrs H. DEVORE, a citizen of the United States, and a residentof the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in J ournal-Bearings for Railroad- Axles,of which the following is a specification. The several features of my invention and the various advantages resulting from their use conjointly or otherwise will be apparent from the following description and claims.

My invention is applicable to the journals of railroad-cars, street-cars, and various descriptions of vehicles running on rails, and it is also applicable to road-vehicles, as wagons, automobiles, 85c.

Inasmuch as a description of my invention in connection with and as applied to a railroad-axle will sufliciently illustrate my invention, I will proceed to describe it in connection with such application.

In the accompanying drawings, making a part of this application and to which reference is hereby made, Figure 1 is a view in perspective of the underside of a journal-box, illustrating myinvention and for convenience of inspection shown upside down. Figv 2 is a View, partly in elevation and partly in section, the section being taken transversely and vertically in the plane of the dotted line 2 2 of Fig. 1. Fig. 3 is a view, partly in section and partly in elevation, the section being a longitudinal one taken in the plane of'th'e dotted line 3 8 of Fig. 1.

In Figs. 2 and 3 there is shown an axle, it being understood that the working position of the combination is inverted.

I will now proceed to describe my invention in detail.

A indicates the axle, of any desired size. Upon this axle are located the car-wheels B in suitable manner. Upon the journal 0 of the axle is located an antifriotion-box D of my invention. This box D has a back or main frame D and a secondary inner separable portion or frame F. The main frame D has recesses for the reception of antifriction-rollers E and these rotate upon and with axlejournals, as E E and E The end journals E are preferably of larger diameter than the middle journals E These journals and the Serial No. 23,712. (No model.)

operation is concerned. The main frame D has end bearings D for the journal E and bearing D for the journal E The secondary or inner separable frame F fits closely within the main frame D of the box and has openings F therein, through each of which projects one of the rollers E. The concave curvature of the separable inner frame F corresponds in general to that of the journal C of axle A. This frame F is arranged to rest, preferably, as follows, viz: at its center F by the same being projected upward, substantially as shown, and at its side F which engages the inner sides of the frame D of the box. Those parts of the inner frame which come opposite to the journals E E heretofore mentioned are respectively shaped so as to come close to those journals and in conjunction with the main frame D hold the rollers E and their journals securely in place. Additional provision for preventing the rollers E from sliding longitudinally is provided in the ridge D which engages the annular groove E in the journal E The inner frame F is held in position by suitable means, a preferred description of which is a dovetail piece or catch G, which engages the edge of the main frame D and the inner frame F, substantially as shown.

The box is arranged to rest upon the journal O and is kept in position by preferred means, and in the present instance on one end by a car-Wheel B and at the other end by an annular flange O at the end of the journal O. The box is provided with suitable means for enabling the antifriction-rollers E to be lubricated and likewise the journal 0 of the axle. One description of such device consists of. the openings H in the top of the box and extending down directly to and over the rollers E, as shown. When the box is in position on the journal, the rollers E bear upon the journal, and it is they which in turn support the car or vehicle body. There is an immense advantage in locating them within the frame F. Heretofore, so far as I am aware, antifriction-rollers have been located upon a journal and not in position in a frame, as F. This frame constitutes the rollers, holds them in proper position, gives security to the movement, and at the same time the rollers E are preferably one, so far as their rollers are protected from injury. The wear and tear also upon the rollers and upon the box is greatly reduced.

In the application of my invention to the journals of railroad-cars and the like I make provision for what is known as the lateral thrust, allowing the rollers sufficient play longitudinally to accommodate themselves to the necessary slip of .the boxes upon the journals in making curves upon the road.

The number of rollers may be increased around a given circle and also the number of rollers may be in creased longitudinally-that is, there maybe three or more upon the same axle E E E or upon the same axial line.

In special instances that feature of my invention which relates to the roller projecting through the inner frame and journal, sub stantially as shown between the frames D and F, there may be one set of rollers instead of two or more.

The rollers constitute important antifriction devices of great value and reduce the friction between the journals and wheels and the journal-bearings to a minimum. Thus higher speed can be obtained and the wear of the journal-bearing is diminished. Consequently the duration of this portion of the running-gear is prolonged.

My invention is simple in construction, economical of manufacture, and easy of application. It is not likely to get out of order.

What I claim as new and of my invention, and desire to secure by Letters Patent, is-

1. An antifriction-box to be used with a journal and consisting of an outer frame D and antifriction-rollers E provided with journals as E E box having recesses for the rollers E and bearings D D for the journals E E and inner separable frame F, fitting within the said frame D and having an inner curvature adapted to receive the journal upon which the box is to rest, the inner frame having openings F through which project rollers E for impingement against the journal, and also having sides F adapted to engage the box D, substantially as and for the purposes specified.

. 2. An antifriction-box to be used with a journal and consisting of an outer frame D and antifriction-rollers E provided with journals as E, E box having recesses for the rollers E, and bearings D D for the journals E E and inner separable frame F, fitting within the said frame D and having an inner curvature adapted to receive the journal upon which the box is to rest, the inner frame having openings I? through which project rollers E for impingement against the journal, and also having sides F adapted to engage the box D, and central projection F adapted to rest against the top of the box D, substantially as and for the purposes specified.

3. An antifriction-box to be used with a eeegi'rs nals as E E box having recesses for the rollers E and bearings D D for the journals E E and inner separable frame F, fitting Within the said frame D and having an inner curvature adapted to receive the journal upon which the box is to rest, the inner frame having openings F through which project rollers E for impingement against the journal, and also having sides F adapted to engage the box D, and central projection F adapted to rest against the top of the box D, and a dovetailed catch G, for engaging the frame D and the inner frame F, substantially as and for the purposes specified.

4. An antifriction-box to be used with a journal and consisting of an outer frame D and antifriction-rollers E provided with journals as E, E box having recesses for the rollers E and bearings D D, for the journals E E and inner separable frame F, fitting Withinthe said frame D and having an inner curvature adapted to receive the journal upon which the box is to rest, the inner frame having openings F through which project rollers E for impingement against the journal, and also having sides 15 adapted to engage the box D, and central projection F adapted to rest against the top of the box D, and means for engaging and holding the box D in position, there being openings H in the back of the box directly over the rollers for lubricating the latter, substantially as and for the purposes specified.

5. The combination of the axle and a box having main frame D containing rollers E, having journals E E the box having bearings D D for the journals E E and inner separable frame F adapted to be within and suitably engage the frame D and having openings F through which the rollersE project and bear upon the journal, and having concave bearing for close conjunction with the journals E E and means for holding the box D and the frame F together, substantially as and for the purposes specified.

6. In combination with a journal, box having outer frame D and rollers as E, each having end bearings, and inner frame F adapted to engage the outer frame D having openings in it through which the rollers project and bear upon the journal, means for holding the first frame to the second, the frame B being provided with suitable concavities forming supplemental bearings for holding the journals of the rollers in position, substantially as and for the purposes specified.
